1.電容器實(shí)際等效電路

  實(shí)際電容器的電路模型如圖1所示,它是由等效電感(ESL)、電容和等效電阻(ESR)構(gòu)成的串聯(lián)網(wǎng)路。電感分量是由引線和電容結(jié)構(gòu)所決定的,電阻是介質(zhì)材料所固有的。電感分量是影響電容頻率特性的主要指標(biāo),因此,在分析實(shí)際電容器的旁路作用時(shí),用LC串聯(lián)網(wǎng)絡(luò)來(lái)等效。

實(shí)際電容器的等效電路

  圖1 實(shí)際電容器的等效電路

  2.對(duì)濾波特性的影響

  實(shí)際電容器的特性如圖2所示,當(dāng)角頻率為1/LC時(shí),會(huì)發(fā)生串聯(lián)諧振,這時(shí)電容的阻抗最小,旁路。超過(guò)諧振點(diǎn)之后,電容器的阻抗特性呈現(xiàn)電感阻抗的特性——隨頻率的升高而增加,旁路效果開(kāi)始變差。這是,作為旁路器件使用的電容器就開(kāi)始失去旁路作用。

實(shí)際電容器的頻率特性

  圖2 實(shí)際電容器的頻率特性

  理想電容的阻抗是隨著頻率的升高而降低,而實(shí)際電容的阻抗具有如圖2所示的頻率特性,在頻率較低時(shí),呈現(xiàn)電容性,即阻抗隨頻率的增加而降低,在某一點(diǎn)發(fā)生諧振,在這點(diǎn)電容的阻抗等于等效串聯(lián)電阻ESR。在諧振點(diǎn)以上,由于ESL的作用,電容阻抗隨著頻率的升高而增加,這是電容呈現(xiàn)電感的阻抗特性。在諧振點(diǎn)以上,由于電容的阻抗增加,因此對(duì)高頻噪聲的旁路作用減弱,甚至消失。

  電容的諧振頻率由ESL和C共同決定,電容值或電感值越大,則諧振頻率越低,也就是電容的高頻濾波效果差。ESL除了與電容器的種類有關(guān)外,電容的引線長(zhǎng)度是一個(gè)十分重要的參數(shù),引線越長(zhǎng),則電感越大,電容的諧振頻率越低。因此在實(shí)際工程中,要使電容器的引線盡量短,電容器的正確安裝方法和不正確安裝方法如圖3所示。

濾波電容的正確安裝與錯(cuò)誤安裝

圖3 濾波電容的正確安裝方法與錯(cuò)誤安裝方法

  根據(jù)LC電路串聯(lián)的原理,諧振點(diǎn)不僅與電感有關(guān),還與電容值有關(guān),電容越大,諧振點(diǎn)越低。許多人認(rèn)為電容器的容值越大,濾波效果越好,這是一種誤解。電容越大對(duì)低頻干擾的效果雖然好,但是由于電容在較低的頻率發(fā)生了諧振,阻抗開(kāi)始隨頻率的升高而增加,因此對(duì)高頻噪聲的旁路效果變差。表1是不同容量瓷片電容的自諧振頻率,電容的引線長(zhǎng)度是1.6mm。

不同電容的自諧振頻率

  

  盡管從濾除高頻噪聲的角度看,不希望有電容諧振,但是電容的諧振并不是總是有害的。當(dāng)要濾除的噪聲頻率確定時(shí),可以通過(guò)調(diào)整電容的容量,使諧振點(diǎn)剛好落在騷擾頻率上。
